Protein name
RecName: Full=Shikimate dehydrogenase (NADP(+));
Gene name

Comments [?]

Function Involved in the biosynthesis of the chorismate, which leads to the biosynthesis of aromatic amino acids. Catalyzes the reversible NADPH linked reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA).
Catalytic activity Shikimate + NADP(+) = 3-dehydroshikimate + NADPH.
Pathway Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 4/7.
Subunit Homodimer.
Similarity Belongs to the shikimate dehydrogenase family.

Comments Aroe in CORGL and CORGB catalyzes the NAD(+)-dependent oxidation of both quinate and shikimate with a higher catalytic efficiency for quinate rather than shikimate, and seems to play a key role in the quinate-degradation pathway (PubMed=18566515).
